Document Summary
Therefore because this phase is e ected everything else is e ected. 3-d description of the ground reaction force vector. Braking phase during rst 1/2 of stance. Propulsion phase during second 1/2 of stance. Vertical component: traditionally depicted by double humps. Accelerate and decelerate the trunk and limb segments in di erent directions. As muscles expend energy, it increases activity by the heart and muscles for breathing. These muscles in themselves also consume energy. Energy expenditure required to maintain upright posture. Minimum energy consumes it an individual is at total rets. The stride length and speed are lower and the cycle time shorter (higher cadence) Small children have no heel strike, initial contact being made by the at foot. There is vert little stance phase knee exion. The e ects of pathological conditions, such as osteoarthritic and parkinsonism which becomes more common with advancing age. Volitional movement commands > under our own musculoskeletal control.
